Tiivistelmä: | It is shown that the efficient frontier of an active invest- ment strategy defined over an asset with only two possible states and a riskless asset is left turning. The intuition that an active investment strategy is superior to a passive strategy whenever the timing ability of the portfolio mana- ger is greater than 50 percent is refuted. Due to the left turning of the efficient frontier, the situ- ation might occur where, under a low risk of tolerance, a portfolio manager would have to decide against his/her timing-ability. This statement is untrue, if a part of the investment is allowed to be invested permanently in a riskless asset. |
